Car cranks but will not start 3-4 times

1998 Dodge Intrepid 1st edition. Car cranks but will not start 3-4 times but then will not even crank at all. No factory alarm but acts like theft deterrent system is engaged. HELP?

No chip in key (it is a original Black key) but the engine will try to start but engine will shut down after 2-3 seconds. It will do this 4 times then engine will not crank at all but will have power inside of car. Not sure how to disarm the theft deterrent system if that is in fact the issue. Or where to even start troubleshooting issue.

We have put a new battery in Fab, New auto shut down relays, lock and unlock doors with original Black key. Left key in ignition at axillary for hours with car hooked up to battery charger.
